Shifting handle 10 is slidable on a rod "i2 on the exterior of the casing, to effect the movements of an arm 13, the forked end of which.. fits between flanges of the screw s indie, such arm being assed through a s ot in the casing and slidable on rod i2. Suitable lugs 14 are provided as bearings forl the latter. it is not necessary to employ locks for retaining the screw in either of its two positions, the pressure of the grain being suliicient for this purpose.

VRAAL- l which the grain deposited from hopper 'lo mounted above the casing i7 of the second STAD, of Buffalo, in the county of Erie and State of New York, have invented certain l screw is fed into the casing of the cross convyeix The casing 1,7 opens laterally into new and useful Improvements in Grain- Conveyors; and l do hereby declare the following to be a full, clear, and exact descri casing l at a point intermediate the outlets 2 and 3, an( opposite such opening the tion of the invention, suc as wild enab e screw 15 is equipped with two arms or wings others skilled in the art to which it appar tains to make and use the same.

This invention relates to that. class of cross conveyors disclosed by Letters Patent No. 827,049, issued to me July 24, 1906, and which .is characterized by the fact that the The shaft of screw l5 carries a gear wlioei 1Q which meshes with a similar gear wheel 2O on shaft 4, so feeder screw is,

that the short conveyei or the cross conveyor, driven constantly in one screw may be rotated in veither direction while the operating shaft revolves continulike the operating shait of direction, the use of reversing mechanism for the driving lgears being unnecessary.

ously in one direction. In the particular machine shown in that patent the grain-was To change the direction of delivery ci the discharged direct into the conveyor casing at one end above one of the outlets, and it was grain by the crossoonveyer, it .is only necessary necessarygn consequence, to close such outto shift the latter longitudinally, to

To all whom it 'may concern:

let when 'the grain was to be delivered from the' other end of the casing. 'A

The primary object of my 'present invention is to avoid the necessity of having to close either outlet, and hence simplify the construction and operation of the conveyer.

A further object is to avoid tue use of all locks for holding the mechanism in place, the pressure of the grain so acting on the screw as to render the use of such locks unnecessary. s

The invention will be hereinafter fully set forth and particularly pointed out in tbe claims.

vIn the accompanying drawings, Figure 1 is a view in erspective. Fig. 2 is a horizontal longitu inal -sectionai view, with parts broken away, Fig. 3 is an end view with a part omitted. Fig. 4 is a plan view partly in section. 4`igs. 5 and 6 are, respectively, cross sectional views on lines 5-5, and 6-6, Fig. 4.

Referring to the drawings, i designates the inclosing casing, which at opposite ends has delivery outlets 2 and Extended centrally through this casing is the operating shaft 4 which is designed to be constantly rotated. in one direction, power being ap-l lace it in engagement with either ofthe two clutches.

From What has been said it will be seen that the grain instead of being delivered directly into the casing of the cross conveyor, is received in the casing of the feeder, and by the latter discharged into the main casing at a point intermediate the two outlets there from. ln consequence no valve for closing either of the outlets is necessary.

l claim as my invention:

1. A conveyor comprising a rotatingr plied, preferably at 5, from any suitable screw, a casing 'therefor having outlets at its source. The screw 6, as pointed out in my opposite ends, means for changing the direc v tion of rotation of the screw, a hopper, and means for feeding grain from the hopper into said casing, said means located wholly at a point intermediate said outlets.

before noted patent, embodies a tubular spindle mounted on shaftA upon which it is capable of being moveddorigitudinally to said shaft, or,

v outlets.
